     • Mathematics and experiments show that light is a transverse wave – the electric and magnetic field vectors point in directions that are perpendicular to the direction of motion of the light wave (and as it turns out, they also rare always perpendicular to each other).

   May 24, 2024 · We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.

   Aug 16, 2021 · In all of these cases, light is modeled as traveling in straight lines called rays. Light may change direction when it encounters objects (such as a mirror) or in passing from one material to another (such as in passing from air to glass), but it then continues in a straight line or as a ray.

   How does light travel in a straight line?

   • The light travels in a straight line directly from the source to your eye. Non-luminous objects, like the Moon, do not produce their own light, but they can be seen because they reflect light from luminous objects. The light travels in a straight line directly from the object to your eye. Ray diagrams are used to show the path that light takes.

   Why is visible light called visible light?

   • Hence, it is called visible light. Since visible light is a form of a wave, it is defined by its characteristic wavelength and frequency. The visible light spectrum is located within a wavelength range of 380 to 740 nanometers (nm) or a frequency range of 405 to 790 terahertz (THz).

   Does light act like a ray?

   • Experiments, as well as our own experiences, show that when light interacts with objects several times as large as its wavelength, it travels in straight lines and acts like a ray. Its wave characteristics are not pronounced in such situations.
